Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION

I agree with RAMM 100%. I previously ran a Crane hydraulic flat tappet cam in my 400. That was a great street cam. It had 222/234 duration and 114 lobe centers. It idled great and made lots of vacuum. It also made 415 HP and 450 TQ in a very mild 400. I stepped up to a 500 stroker, and read all about cubic inches masking the effects of a larger cam. I put in a Comp hydraulic roller with 236/242 duration and 110 lobe centers. It has a noticeable lope at idle and pulls about 8.5 inches of vacuum in gear. The rest of the car is built to accommodate it so it is not an issue, but I expected better with the increase in cubes.
